A) \[6.626\times {{10}^{-22}}kg\,\,m/s\]
B) \[3.45\times {{10}^{-25}}kg\,\,m/s\]
C) \[3.313\times {{10}^{-22}}kg\,\,m/s\]
D) \[2.126\times {{10}^{-23}}kg\,\,m/s\]
Correct Answer: A
Solution :
The momentum is given by, \[p=\frac{h}{\lambda }=\frac{6.62\times {{10}^{-34}}}{0.01\times {{10}^{-10}}}\] \[\left( \begin{align} & here\,\,wavelength\,\,\lambda =0.01\,\,\overset{\text{o}}{\mathop{\text{A}}}\, \\ & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,=0.01\times {{10}^{-10}}m \\ \end{align} \right)\] \[=6.62\times {{10}^{-22}}\text{kg}\,\,\text{m}/\sec \]
